.   5     .

How can i get it?

This will decrease the page number by one:

\addtocounter{page}{-1}

This will suppress the page number on the current page: (which you can leave out if the page number currently doesn't show up)

\thispagestyle{empty}

So, you can put together your own macro (I'm calling it \mypart but name it what you like) to do all three things at once:

\newcommand{\mypart}[1]{\part{#1}\addtocounter{page}{-1}\thispagestyle{empty}}
